PRESSlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 615,397, dated December 6, 1898'.

Application filed May 7, 1897. Serial No. 635,477. (No model.)

To all whom it may concern;

Be it known that we, PIERRE LORILLARD, Jr. of Tuxedo Park, in the county of Oran'ge, and EDWARD G. TREMAINE, of New York, (Brooklyn,) in the county of Kings and State of New York, have invented a certain new and useful Improvement in Pressing Machines, of which the following is a specification.

A machine embodying the improvement Will be described, and then the novel features will be pointed out in the claims.

In the accompanying drawings is illustrated a structure embodying our invention, in which- Figure 1 is a plan or top view of a pressingmachine embodying the improvement. Fig. 2 is a front View, on an enlarged scale, of a portion of the machine. Fig. 3 is a vertical section on the plane of the dotted lines 3 3 of Fig. l, and Figs. 4:, 5, 6, 7, 8, 9, and 10 are vertical sections taken radially and illustrating parts in different positions.

Similar letters of reference designate responding parts in all the figures.

Referring to said figures in detail, A designates a stationary base made in the form of a circular track. From the inner side of this extend a number of radial arms or spokes A, which are connected with a hub A B B designate a carriage, here shown as comprising two rings B B and connections between them, the latter being omitted from the drawings to avoid unnecessary complication, as they may be of any desirable form as, for example, ordinary tie-rods. The ring B rests upon the rollers B, which are supported on the top of the base-piece A. From the ring B extend arms or spokes B to a ring 13. This ring 13 is connected by a number of radial arms B to a ring B The latter is fastened to a hub B which intermediate of its outer ends is provided with a shoulder b and below this shoulder fits within the hub A of the stationary base A. Preferably ballbearings will be used between the horizontal surfaces where the weightof the carriage B B and its appurtenances is more or less supported.

Intermediate the two rings B B and formcoring a part of the carriage which comprises these rings are a number of cylinders C, preferably with rams 0, upon the upper end of each of which is a platform D, upon which is carried the material to be pressed, said material being placed in the molding-cavities e of a frame E on said platform. Above the platform D and connected to the ring B is a block d, to which is secured a series of blocks (1', corresponding in shape to the size of the matrices or molding-cavities e of the frame E.

6 represents a framework having ends projecting through the platform D and running on a track e which is supported by a series of arms a The frame E, having the series of molding-cavities, is attached to the end of a link e, connected to an arm c pivoted to a projection e from the radial arms B This arm e has secured to it an arm 6 journaled on one end of which is a'roller e bearing againstra cam-surface e", the said roller being maintained in contact with the cam-surface by means of a spring 6 secured at one end to the arm 6 and at the other end to a pin c,

projecting from the arm B Liquid is supplied through a number of radial tubes 0 to the hydraulic cylinders beneath the rams or plungers c. The hub B of the carriage B B is made hollow or preferably with a chamber I), through which liquid may be supplied to the pipes 0 As here shown, the liquid may enter from the bottom of the hub and be supplied from any suitable source. Combined with the pipes c are inlet and outlet valves 0 0 having downwardlyprojecting stems, which coact with stationary cams c c affixed to that one of the arms or spokes A which is just to the left of the front of the machine. Similar cams (not shown and forming a second set) are arranged upon another of these arms or spokes. In this example of the improvement the carriage rotates to the left, or, in other words, as indicated by the arrow in Fig. 1. the presses has passed to the left of the front of the machine its valves 0 0 will be acted upon by the cams c 0 so as to close the outlet-valve and open the inlet-Valve, thus allowing liquid to pass to the ram and force the same upwardly relatively to the stationary After each of top. After the movement of the carriage shall have carried the inlet-valve beyond its cam the latter will close and retain the liquid in the ram-cylinder. Thus the pressure will be maintained until the travel of the carriage has brought the valves 0 c of that ram over the second set of cams, whereupon the outlet-valve will be open, the inlet-valve remaining closed.

The operation of the device is as follows: Each of the platforms D is provided with an extended portion located outside of the circle of the series of presses. In Fig. 4 the frame E is shown as in its first position, the arm 6 having been operated by its connections to the cam-surface e to take up its first position, as shown in said figure, wherein the frame E is supported upon the extended portion of the platform D and has received the quantity of material to be pressed in its several molding-cavities. The revolution of the carriage B 13 brings the friction-roller of the arme in contact with a depression in the cam-surface a", so that the arm a by the action of the spring 6 draws the frame through its connecting-link e fromthe position shown in Fig. 4 to the position shown in Fig. 5.

Further revolution of the carriage causes the opening of the valve to admit pressure to the hydraulic cylinder, whereupon the ram is lifted and the material contained in the matrices or molding-cavities of the frame E is pressed against the blocks 01, as shown in Fig. 6. Approximately simultaneously with this action the roller on the frame 6 comes in contact with a raised portion of the track e so that the frame 6 is raised with the frame E to the position shown in Fig. 6. The lifted portion of the track e is continued partially around the circle to a point beyond the point where the exhaust-valve of the hydraulic cylinder operates, so that after the hydraulic cylinder has returned to its original position the frame E is supported in its upper position by the framework e, the blocks of pressed material resting on the platform D, which position of the parts is shown in Fig. 7.

Figs. 8, 9, and 10 illustrate successive positions of the different parts which are brought about by the action of the cam-surfaces of the track a and the cam-surface e. In .Fig. 8 the cam-surface 6 operating upon the link c, has caused the pressed material to be pushed outwardly upon the extended portion of the platform D, while the track 6 maintains the frame 9 in its upper position. In Fig. 9 the spring 6 has withdrawn the arm arm 6 and link 6 so that the frame E is in its outermost position again to receive the supply of material to be pressed and repeat the operation.

Any suitable means may be employed for imparting rotary motion to the carriage B B In the present instance we have shown a gearring F affixed to. the ring B and adapted to be driven by a pinion.

It will be understood that the various elevations and depressions of the several camsurfaces are adjusted so as to operate in proper relative time the different movements of the frame E and the frame 6, as well as the raising and lowering of the platform D.

What We claim as our invention, and desire to secure by Letters Patent, is-

1.. The combination of a movable carriage, a number of presses supported by said car riage, means for causing the operation of the presses successively, frames for receiving the material to be pressed and carrying it into the presses, and means for supporting the frames in an elevated position while the bottoms of the presses are lowered, substantially as specified.

2. The combination of a rotary carriage supporting a number of presses, means for causing the operation of the presses successively as the carriage is rotated, a frame for each of such presses for receiving the material to be pressed and carrying it into the presses, means for moving each frame out of position after the material has been pressed, and means for moving the pressed material out of the press, substantially as specified.

3. The combination of a movable carriage supporting a number of presses, frames for receiving the material to be pressed, means for operating said frames to bring them to position to receive charges of material and then into position to have the material pressed, means in connection with each of the frames for raising them after the material has been pressed to permit the pressed material to be moved out of the press and then lowering the frames, and means for moving the pressed material out of the press, substantially as described.

4. The combination of a circular carriage comprising an upper and lower ring, a number of presses supported on said carriage, the fixed part of said press being carried by one ring and the movable part by the other ring, means for operating the movable part of said carriage, said means being put in operation as the carriage is rotated, a sliding frame for e and connecting-link e to its first position again, and the frame 6 has also returned to its first position by reason of a depression in the track 6 permitting it to assume such a position so that the catch 6 on said frame engages the block 6 of the link 6 The next operation is that of pushing out the frame E to its first position, which is accomplished by an elevation in the cam-surface e", effecting a forward movement of the arm e,

containing the material to be pressed earned by the movable part of the press, and means ,in connection with the frame for moving it in and out of position from under the fixed part, said means being operated as the carriage is rotated, substantially as described.
